This is a division of application Ser. No. 423,607, filed Oct. 17, 1989, now U.S. Pat. No. 4,988,729, which is a continuation of application Ser. No. 184,865, filed Apr. 22, 1988, now abandoned.

The invention relates to the use of substituted aminomethylheterocyclic compounds, some of which are known, as pesticides.

It has already been disclosed that certain aminomethylheterocyclic compounds, such as, for example, tetrahydro-N,5-dimethyl-furfurylamine or 2,2-dimethyl-N-isopropyl-1,3-dioxolane-4-methanamine or N,2-dimethyl-1,3-oxathiolane-5-methanamine, or its hydrochloride, or cis-N-t-butyl-5-methyl-furfurylamine or N-cyclohexyl-2-methyl-2-phenyl-1,3-dioxolane-4-methanamine, inter alia, have certain pharmacological properties, such as, for example, antihypertensive, saluretic, parasympatholytic or muscarinergic properties or are used as intermediates in the preparation of pharmacologically active compounds (cf., for example, GB 1,031,916; DE-OS (German Published Specification) 2,810,732, DE-OS (German Published Specification) 2,757,922; Tetrahedron 33, 1309-1319 [1977]; Acta Pol. Pharm. 39, 33-39 [1982] or Europ. J. Med. Chem./Chim. Ther. 19, 495-500 [1984], inter alia).

Nothing is hitherto known on the activity of these previously known compounds as pesticides.

It has furthermore been disclosed that certain aminoketals, such as, for example, 2-[3-(4-chlorophenoxy)-2-methyl-prop-2-yl]-2-methyl-4-[N,N-(di-n-butyl)-aminomethyl]-dioxolane or 2-[3-(4-methyl-phenoxy)-2-methyl-prop-2-yl]-2-methyl-4-[N,N-(di-n-butyl)-aminomethyl]-dioxolane or 2-[3-(4-chlorophenoxy)-2-methyl-prop-2-yl]-2-methyl-4-[N-methyl-N-(3-methyl-but-2-en-1-yl)-aminomethyl]-dioxolane, have good fungicidal properties (cf. EP 97,822).

However, the activity of these previously known compounds is not completely satisfactory in all areas of application, in particular at low application rates and concentrations.

It has been found that the substituted aminomethylheterocyclic compounds of the general formula (I) ##STR2## in which R¹ represents hydrogen, alkyl, alkenyl, in each case optionally substituted tetrahydronaphthyl, decahydronaphthyl, cycloalkyl or cycloalkenyl, furthermore alkyl which is substituted by cycloalkyl, cycloalkenyl, cycloalkyloxy or cycloalkylthio, where the cyclic radicals may optionally be substituted, furthermore optionally substituted aryl, in addition alkyl which is substituted by aryl, aryloxy, arylthio, arylsulphinyl or arylsulphonyl, or alkenyl which is substituted by aryl, where the aryl radicals may in each case optionally be substituted;

R² represents hydrogen qr methyl,

R³ represents alkyl, alkenyl, alkinyl, alkoxyalkyl, hydroxyalkyl, hydroxyalkoxyalkyl, dialkoxyalkyl, or in each case optionally substituted cycloalkyl, cycloalkylalkyl, aryl, aralkyl, aralkenyl, furanylalkyl, tetrahydrofuranylalkyl, tetrahydropyranylalkyl, dioxolanylalkyl or dioxanylalkyl, and

X represents oxygen, sulphur or a CH₂ group,

some of which are known, and the acid addition salts thereof have a good action against pests, in particular against fungal pests.

The compounds of the formula (I) can exist as geometrical and/or optical isomers or isomer mixtures of various composition. The pure isomers and the isomer mixtures are claimed according to the invention.

Surprisingly, the substituted aminomethylheterocyclic compounds of the general formula (I) which can be used according to the invention exhibit a better activity against fungal pests than do the aminoketals which are known from the prior art, such as, for example, 2-[3-(4-chlorophenoxy)-2-methyl-prop-2-yl]-2-methyl-4-[N,N-(di-n-butyl)-aminomethyl]-dioxolane or 2-[3-(4-methylphenoxy)-2-methyl-prop-2-yl]-2-methyl-4-[N,N-(di-n-butyl)-aminomethyl]-dioxolane or 2-[3-(4-chlorophenoxy)-2-methyl-prop-2-yl]-2-methyl-4-[N-methyl-N-(3-methyl-but-2-en-1-yl)-aminomethyl]-dioxolane, which are similar compounds chemically and in view of their action.

The substituted aminomethylheterocyclic compounds of the formula (Ia-1) are compounds according to the invention and can be obtained with the aid of preparation process (a).

Suitable diluents for carrying out preparation process (a) are inert organic solvents. These include, in particular, aliphatic, alicyclic or aromatic, optionally halogenated hydrocarbons, such as, for example, benzine, benzene, toluene, xylene, chlorobenzene, petroleum ether, hexane, cyclohexane, dichloromethane, chloroform, carbon tetrachloride, ethers, such as diethyl ether, dioxane, tetrahydrofuran or ethylene glycol dimethyl or diethyl ether, ketones, such as acetone or butanone, nitriles, such as acetonitrile or propionitrile, amides, such as dimethylformamide, dimethylacetamide, N-methylformanilide, N-methylpyrrolidone or hexamethylphosphoric triamide, esters, such as ethyl acetate, sulphoxides, such as dimethyl sulphoxide, or alcohols, such as propanol or butanol. However, preparation process (a) can also be carried out without addition of a diluent.

Suitable acid-binding agents for carrying out preparation process (a) are all inorganic and organic bases which can conventionally be used. Alkali metal hydrides, hydroxides, amides, carbonates or hydrogen carbonates, such as, for example, sodium hydride, sodium amide, sodium hydroxide, sodium carbonate or sodium hydrogen carbonate, or alternatively tertiary amines, such as, for example, triethylamine, N,N-dimethylaniline, pyridine, 4-(N,N-dimethylamino)-pyridine, diazabicyclooctane (DABCO), diazabicyclononene (DBN) or diazabicycloundecene (DBU), are preferably used.

The reaction is carried out and the reaction products of the formula (Ia) are worked up and isolated by conventional methods.

Suitable diluents for carrying out preparation process (b) are likewise inert organic solvents. These include, in particular, aliphatic or alicyclic, optionally halogenated hydrocarbons, such as, for example, benzine, petroleum ether, hexane or cyclohexane; ethers, such as diethyl ether, dioxane, tetrahydrofuran or ethylene glycol dimethyl or diethyl ether; esters, such as ethyl acetate, or alcohols, such as methanol, ethanol or isopropanol.

The reaction temperatures may be varied within a relatively wide range when carrying out the preparation process. In general, the process is carried out at temperatures between 20° C. and 250° C., preferably at temperatures between 20° C. and 200° C.

Preparation process (b) is carried out, if appropriate, under increased pressure. In general, the process is carried out in a pressure range between 1 and 250 atm, preferably between 1 and 150 atm.

To carry out preparation process (b), 0.001 to 0.1 mole, preferably 0.01 to 0.05 mole, of hydrogenation catalyst are added per mole of substituted aminomethylheterocyclic compound of the formula (Ia-1), and hydrogen is added in an autoclave until the necessary pressure has been reached. The reaction is carried out and the reaction products are worked up and isolated by conventional methods.

At the same time, the active compounds which can be used according to the invention also have a systemic activity in addition to good protective properties. In addition, the active compounds which can be used according to the invention have a good bactericidal action and an excellent in vitro activity.

Depending on their particular physical and /or chemical properties, the active compounds can be converted to the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, natural and synthetic materials impregnated with active compound, very fine capsules in polymeric substances and in coating compositions for seed, and furthermore in formulations used with burning equipment, such as, fumigating cartridges, fumigating cans, fumigating coils and the like, as well as ULV cold mist and warm mist formulations.

For the treatment of soil, active compound concentrations of 0.00001 to 0.1% by weight, preferably 0.0001 to 0.02% by weight, are required at the place of action.
